Does this sound like the set of challenges you might be facing?

  • This is a one-way door
  • I keep treating this choice like I can run the numbers on it, but the honest truth is nobody actually knows the odds here
  • I keep playing out this decision in my head as if there’s just one way it goes
  • My whole mind flips between "I don’t know enough to move" and "okay now I finally know enough" with nothing in between
  • I have to split my time and money across several bets and I genuinely can’t tell which will pay off, yet I keep agonizing over the perfect breakdown

Practices that may help

  1. Use maximin reasoning for high-stakes, irreversible decisions under ambiguity
    Choose the option whose worst plausible outcome is most survivable — when you can’t compute expected value, optimize the floor.

  2. Distinguish risk from ambiguity before reacting
    Label whether you’re facing known odds or genuinely unknown odds — the right tool depends on the answer.

  3. Expected Value Thinking: Deciding Under Uncertainty
    Expected value thinking multiplies each possible outcome by its probability and sums the results, giving a single number that represents the average payoff of a decision. It is the mathematical foundation of rational decision-making under uncertainty — well grounded in decision theory — but it has real limits: probabilities are often uncertain, outcomes are not always quantifiable, and raw expected value ignores risk aversion that can be legitimate.
  4. Enumerate scenarios and their probabilities before deciding
    Write down each meaningful outcome, assign a probability, and compute the weighted total.

  5. Update incrementally as evidence arrives rather than waiting for certainty
    State your current best-guess probability, identify what would shift it, and update when that evidence arrives.

  6. Use the 1/N rule for diversification under deep uncertainty
    When you cannot estimate the value of each option reliably, spread resources equally.

  7. Run small bets to convert ambiguity into data
    Replace paralysis with cheap experiments that generate local evidence and reduce uncertainty incrementally.

  8. Use "take the best": choose on your single most informative cue
    When choosing between options, identify the most diagnostic cue and use it — stop searching for more.

  9. Look for decisions with asymmetric upside — large potential gain, small defined loss
    Seek situations where the worst case is bounded and small while the best case is large and open-ended.

  10. Log the information you wished you had
    In every decision entry, write: what would I want to know that I don’t?
